Crust-agents drift. The Reef remembers.

Your agents drift. The Reef remembers.

A local-first task manager that gives AI agent teams persistent memory, structured state, and human-steerable coordination.

The drift problem

Compaction drift

Context windows fill up. Summaries replace details. Decisions fade.

Attention drift

Even in-context, LLMs lose the middle. Important state gets lost in the noise.

Cold start amnesia

New sessions start blank. Your agent doesn't remember yesterday.

How the Reef works

01

Structure your state

Tasks, projects, and decisions live in a persistent local store — not in a context window. The Reef is the source of truth.

02

Agents read and write

When an agent wakes up, it reads from the Reef. When it finishes work, it writes back. Memory survives compaction, restarts, and model switches.

03

Humans steer

Browse the memory DAG. Pin important decisions. Override agent plans. You see what the agent sees — and you can correct it.

Built for agent operators

Memory DAG

Hierarchical summarization tree. See how your agent compressed context. Expand any node to the original messages.

Visual Reef

A living graph of your pods, projects, and tasks. Drag, zoom, and explore the structure your agents built.

Canvas

Infinite whiteboard with JSON Canvas support. Map ideas, connect concepts, import/export.

Kanban

Flexible columns per pod. Drag tasks across status lanes. Scales with your window.

Dark-native

Designed dark from day one. Not a light theme with a dark paint job. WCAG AA contrast throughout.

Local-first

SQLite on your Mac. No cloud required. No subscription. Your data never leaves your machine.

Who Reef is for

AI engineers

Building with Claude, GPT, or open-source models? Reef gives your agents persistent memory without managing a database.

Agent operators

Running multi-agent teams? Reef is the coordination surface — task assignment, state tracking, memory inspection.

Power users

Using AI assistants daily? Reef captures what your assistant forgets between sessions.

Stop losing context.
